Bitcoin CAN NOT be a good storage of value, because the PoW mining expense is way too high. By holding Bitcoin, you are basically charged a 10% tax each year. That's not a good storage of value. Bitcoin can become a good storage value if it converts to a Proof of Stake network.
It is my understanding that most PoS coins use PoW for initial coin distribution. Bitcoin is still not generally regarded a viable, so the continued coin distribution is justified, IMO. The 10% tax will be reduced to a 5% tax within 3 years.
The "unfair" wealth of the "early adopters" is a common criticism I hear about Bitcoin. You appear to be arguing that the early adopters should control even more of the wealth.
